Abstract (en)
A packet-based wireless system is configured in accordance with a cell pattern which utilizes multi-sector directional cells. An illustrative embodiment utilizes a five-sector cell pattern, with five approximately 72 DEG directional antennas in the base station of each cell. The assignment of frequency channels to cell sectors in the cell pattern repeats itself in six-cell groups throughout the system. This cell pattern allows the system to utilize a frequency reuse factor of one, such that substantially the same set of communication channels may be used in each cell of the system. In other possible implementations of the cell pattern, the sector positions of the directional antennas may be arranged such that the sectors in a given cell are rotated by an integer or non-integer number of sectors relative to the sectors of a neighboring cell, or the sector positions of the directional antennas may be fixed for all of the cells. The invention can be used to increase the capacity of a non-CDMA wireless system without significantly increasing co-channel interference. <IMAGE>
